Cum Melon
When a chick has a dude or several dudes cum so much in her ass, that squeezing it causes it to leak like a ripe melon.
"After having those three dudes over last night, Cheryl became such a cum melon!"
"Yeah dude. When she sat down, you heard the loud squish coming from her butt hole before she ran off dripping."
